Description
As a new method to enhance nanosecond pulsed power, aiming improvement of cold plasma applications, we designed a type of circuit that is amplified by synchronization of double simple inductive energy storage (IES) circuits with a semiconductor opening switch (SOS) diode. Secondary circuits of simple IES circuits which consist of capacitors, a pulse transformer, MOS-gated thyristors, and a SOS, were connected in parallel and in series, and power amplification has been succeeded at low repetition rate by synchronization of reverse currents through the SOS diodes in two circuits. However, there are some problems, e.g., synchronization deviation by variation of load and repletion rate, difficulty of circuit adjustment for synchronization, and low efficiency. Aiming to those improvement, characterization of the pulsed power generator was carried out by spice simulation and experimental circuit estimation. Our presentation details current and energy transfer path in the circuit including parasitic components, which were obtained from the circuit characterization.
